Re: How to immutably initialize parent object with private fields?

[lscrd]

In this direction, to make it work, you have to do a cast:
    
    
    proc newElementA(): ElementA =
      cast[ElementA](newElement("A"))
    
    
    Run

Another way consists to create a proc _initElement_ in _lib_ :
    
    
    proc initElement*(elem: Element, id: string) =
      elem.id = id
    
    
    Run

then to define _newElementA_ this way:
    
    
    proc newElementA(): ElementA =
      new result
      result.initElement("A")
    
    
    Run
